Original Abstract

Interactions of nitrates with humic acids are studied by means of flow-through coulometry. It was found that nitrates are adsorbed mainly by solid humic particles and a small amount is bonded to dissolved humic macromolecules or aggregates. Langmuir and Freundlich adsorption isotherms were tested for mathematical description. Two linear regions were observed in the case of both used models for normalized coordinates. The intersection is the same for both isotherms and corresponds with the measured adsorption maximum (80% adsorbed). It indicates two principal sites for nitrate adsorption.
